PerfLabTests.LowLevelPerf.ForeachOverList100Elements

Description of detection logic

IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsRegressionBase: Marked as not a regression because the compare was not 5% greater than the baseline, or the value was too small.
IsImprovementBase: Marked as improvement because the compare was 5% less than the baseline, and the value was not too small.
IsImprovementCheck: Marked as improvement because the three check build points were 0.05 less than the baseline.
IsImprovementWindowed:Marked as improvement because 8.711675961538463 < 10.112381754836308.
IsChangePoint: Marked as a change because one of 3/15/2022 12:53:39 AM, 3/22/2022 2:14:22 AM falls between 3/13/2022 11:50:20 AM and 3/22/2022 2:14:22 AM.
IsImprovementStdDev: Marked as improvement because 171.6539235421897 (T) = (0 -8713482.518937865) / Math.Sqrt((30899917090.418278 / (299)) + (12492440.696085857 / (34))) is greater than 1.9671567996108528 = MathNet.Numerics.Distributions.StudentT.InvCDF(0, 1, (299) + (34) - 2, .975) and 0.16709747171038972 = (10461587.308218714 - 8713482.518937865) / 10461587.308218714 is greater than 0.05.
